    Abstract: A plasma processing device may include a plasma processing chamber, a plasma electrode assembly, a wafer stage, a plasma producing gas inlet, a plurality of vacuum ports, at least one vacuum pump, and a multi-port valve assembly. The multi-port valve assembly may comprise a movable seal plate positioned in the plasma processing chamber. The movable seal plate may comprise a transverse port sealing surface that is shaped and sized to completely overlap the plurality of vacuum ports in a closed state, to partially overlap the plurality of vacuum ports in a partially open state, and to avoid substantial overlap of the plurality of vacuum ports in an open state. The multi-port valve assembly may comprise a transverse actuator coupled to the movable seal plate and a sealing actuator coupled to the movable seal plate.

    Abstract: A confinement ring for use in a plasma processing chamber includes an upper horizontal section, an upper vertical section, a mid-section, a lower vertical section, a lower horizontal section and a vertical extension. The upper horizontal section extends between an inner upper radius and a first outer radius of the confinement ring. The mid-section extends between inner upper radius and a second outer radius of the confinement ring. The lower horizontal section extends between an inner lower radius and the second outer radius, and the vertical extension extends down from the lower horizontal section proximate to the inner lower radius. The upper vertical section extends between the upper horizontal section and the mid-section proximate to the inner upper radius, and the lower vertical section extends between the mid-section and the lower horizontal section proximate to the second outer radius.

    Abstract: A substrate processing system configured to process substrates includes a substrate transport assembly that encloses a controlled environment defined within a continuous transport volume and at least two process modules coupled to the substrate transport assembly. The substrate transport assembly is configured to transport substrates to and from the at least two process modules through the continuous transport volume. At least two gas boxes are configured to deliver gas mixtures to the at least two process modules. An exhaust duct configured to selectively evacuate the at least two process modules through the at least two gas boxes. Surfaces of the at least two gas boxes include perforations configured to allow gases to flow from the at least two gas boxes into the exhaust duct.
